[Samba] Winbind and getent issues

[Jeremy Farrar]

I am currently setting up a cluster of Samba servers using DRBD and CTDB. I
have gotten the DRBD and CTDB configured on my cluster. I have configured
Samba and Winbind to join my active directory domain. Right now I am
struggling to get authentication through Winbind to work. My /var/log/secure
file looks like my system is not even trying to authenticate against AD.

wbinfo -u work great as does wbinfo -g. I am able to successfully
authenticate withe wbinfo -a [Username]%[Password]. getent password and
getent group do not function.

I checked the following links based upon documentation I have read.

ls -la /lib | grep winbind
lrwxrwxrwx  1 root root      24 May 11 14:52 libnss_winbind.so ->
/lib64/libnss_winbind.so
lrwxrwxrwx  1 root root      24 May 11 14:52 libnss_winbind.so.2 ->
/lib64/libnss_winbind.so

Any help would be greatly appreciated. Thanks.
